Running mean of a vectorEike Luedeling
In this paper,the time-like surface with parallel mean curvature vector in 4-dimensional Minkowski space R3,1 is expressed by means of integrable system.Being different from space-like surface,the time-like surface is determined by a kind of Klein-Gordon equations:ωxy+|H|sinhω=0,ωxy-|H...

This paper considers the problems of estimating a mean vector [mu] under constraint [mu]'[Sigma]-1[mu] = 1 or [Sigma]-1/2[mu] = c and derives the best equivariant estimators under the loss (a - [mu])' [Sigma]-1(a - [mu]), which dominate the MLE's uniformly. The results ...
But take my word for it that it's real, English language text. The data is in the form of a vector of strings, which we'll call x. x = readRDS("x.rds") length(x) ## [1] 655760 sum(nchar(x)) ## [1] 162663972 library(meanr) system.time(s <- score(x)) ## user ...
We consider these cases in the context of finding the number of components of the mean vector that may be different from zero in one-sample multivariate analysis. In fact, we consider this problem in more generality by considering it as a growth curve model introduced in Rao (1959) and ...
The problem of hypothesis testing concerning the mean vector for high dimensional data has been investigated by many authors. They have proposed several test criteria and obtained their asymptotic distributions, under somewhat restrictive conditions, when both the sample size and the dimension tend to ...
